Today I am going to talk about Earth Hour.
I think that Earth Hour is  to save the world as we must OFF all electricity

I think is at 28 march 

I think people are organising this event to save the Earth 
During this Earth Hour, everyone will try to off all the lights to save the Earth and save electricity
I can organise activities like don't on any fan 

The layer that is covering the Earth from the sun is getting bigger and bigger and the whole Earth is also getting hotter and hotter.
I think to prevent the Earth from getting hotter and hotter by using non-electrical appliances
